Patented May 6.' i 913.

Application filed July 16, 1912. Serial No. 709,751.

To all whom it may concern.'

Be it known that I, WALTER HAMMioii, a

Acitizen of the United Sta-tes, residing at Pittsburg, in the county ofCrawford and State of Kansas, have invented a new and usefulGas-Producer, of which the following is a specification. 1

The device herein disclosed is adapted t be used for the making of gas,and the invention aims to provide novel means for creating a draft andfor disposing of the gas, and to provide novel mechanism whereby theaforesaid means, anda coal trimmer, may be actuated simultaneously.

`With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of vparts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be "made within thescope of what is claimed without departing from the spirit of theinvention.

The drawings show a side elevation partly in section of the completeapparatus.

In the drawings` :20 designates a cylindrical furnace. the lowerterminal 21 of which is embraced by the flange 14,of a conical fire box15, provided with a grate 15a, the lower flange 18 of the fire box beingreceived in the upper end of an ash pit 16, the lower end of whichcarries a slidable ash door 17. Legs 10 are provided, and the flanges 11of the legs are secured to the parts 14 and 21 of the .tire box l5 andthe furnace 20 respectively. Braces 19, which may be angle irons,connect the legs 10 with the upper end of the ash pit 16.

The upper terminal 22 of the furnace 20 is closed by a cover 24 providedwith a flange 25 which embraces the furnace. The cover 24 is providedwith an obliquely disposed intake chute 24', the passage of coal throughthe 'saine being controlled by a shutter which is pivotally supported onthe cover 24.

In the side wall of the furnace 20 there is a stoke opening 39,controlled by a closure 39a. The closure may be provided with anopening, across which a plate mica extends to permit the gas producingoperation to be observed.

The last specified details are Well known in the art and need noillustration.

A spider-.28 is connectedperipherally to the furnace 20, at a pointadjacent the up.-

per end ofthe furnace. The Vdischarge end 2G of the intake chute 24extends below vthe spider 28. The spider supports a shaft 29, the lowerterminal. of which is reduced and screwfthreaded as at 33, to receive anut 32 engaging the hubof a coal leveler 31'which is keyed to the shaft29. The hub of the leyeler 31 engages the hub ofthe spider 28 and tliusthe shaft 29 is held against upward movement. The leveler 31 is shapedlike the propeller wheel of a vessel.

A.l draft through the furnace 2O is maintained by afan 34 driven by amotor 34a mounted upon a frame 35, there being a conduit 36 connectingthe fan 34 with an opening 37 in the fire Abox 15, the opening 37 beingprotected by a screen 3S which prevents.

ash and braize from entering the conduit.

The gas is removed through a conduit- 40 which communicates with anopening 4l disposed adjacent the upper end of the furnace 20, theopening being protected by a screen 42' which prevents the ash or braizefrom entering the conduit 40. Suction is created in the conduit 40 by afan 41 having an out let 41". The fan 41 lis supported by the upper bar44 ofthe frame The fan 41 is driven from the motor 34a by a belt 46which passes over a sheave 47 secured to the shaft 41a ofthe fan 41.Beveled gears 4S connect the shaft 41a with an upright shaft tcarry inga sheave 50 which drives a belt QQ the belt 2.9 being trained about astre/avc 30 which is secured to the end of the shaft 29, .wherebyrotation is imparted to the coal leveler 31. It will be noted that bythis constructionthe fans 41 and 34 and the coal leveler 31 may bedriven from a common source of energy which may be the niotor 34a, thesaine being of any suitable character. 1n practical operation, aninitial charge of coalis placed in the fire box 15, and the .tire islighted. Subsequently, the vcoal is fed through the chute Q4 althoughthe coal may be fed through the opening 39 if desired. The coal, passingthrough the discharge end 26 of the chute 24, is delivered below thespider 2S and upon the leveler 31 which, rotated rapidly, vwilldistribute the coal iwithin the furnace 20. The ashes forming upon thegrate 15i will drop into the ash pit 16, the

slidable door 17 permitting the removal of the ashes at any time. lVhenthe motor 34 is inoperation, the belt 46will be actuated, rotation beingimparted to the sheave 47 and to the shaft 41l1 of the fan 41. When 5tatory l5 VArgasi" producer comprising 'a furnace,.a

{he shaft 41a of the fan 41 is actuatcd,vrota ion will loe-imparted tothe shaft 49, through shaft 49 and tothe the medium of the pulleys()andv 50,l and the belt 29. rIhe motor-34, of course, drives the fan 34.Thefan 34 createsa' forced draft 10 to the coal inthe fire box- 15, 'and.the fan 4&5 creates a suction which draws away thef gas, the:` gasbeing discharged through the outlet 41. v t a WhaLSnlaimed is:
